We define a moduli functor parametrizing finite maps from a projective (locally) Cohen-Macaulay curve to a fixed projective space. The definition of the functor includes a number of technical conditions, but the most important is that the map is almost everywhere an isomorphism onto its image. The motivation for this definition comes from trying to interpolate between the Hilbert scheme and the Kontsevich mapping space. The main result is that our functor is represented by a proper algebraic space. As applications we obtain a new proof of the existence of Macaulayfications for varieties, and secondly, interesting compactifications of the spaces of smooth curves in projective space. We illustrate this in the case of rational quartics, where the resulting space appears easier than the Hilbert scheme. / QC 20101022

Through the study of selected works written by Earle Birney, Phyllis Webb, and Leonard Cohen, this thesis seeks to interrogate the wave of modern Canadian nationalism and culture construction that grew as a result of the loosening ties to British roots, the increasing infiltration of American influence, and the political climate following the Second World War. As the Cold War began to take root, Canada found itself amid not only a political conflict, but also a barrage of emerging mass media on a global scale. As a result of this crossfire of national voices, the Canadian culturati made efforts to join in the conversation—through national radio, film, literature, and the creation of a new flag and dictionary—but before the nation could speak, it had to answer the questions that dominated the era: Who is Canada? What is the voice of Canada? Whose voice speaks for the nation? This thesis aims to study the evolution of the answers that were given to these questions. Through the lens of nationalist theory, translation theory, and the postcolonial Gothic, this thesis traces a route from Birney’s attempt to create a nation within a perceived “lack of ghosts,” to Webb’s efforts to question the very question of nationalism, ultimately to Cohen’s illumination of the internal mechanics of national identity as he worked to reconstruct it in a movement toward the Clear Light.

In my dissertation, I present Hermann Cohen's foundation for the history and philosophy of science. My investigation begins with Cohen's formulation of a neo-Kantian epistemology. I analyze Cohen's early work, especially his contributions to 19th century debates about the theory of knowledge. I conclude by examining Cohen's mature theory of science in two works, The Principle of the Infinitesimal Method and its History of 1883, and Cohen's extensive 1914 Introduction to Friedrich Lange's History of Materialism. In the former, Cohen gives an historical and philosophical analysis of the foundations of the infinitesimal method in mathematics. In the latter, Cohen presents a detailed account of Heinrich Hertz's Principles of Mechanics of 1894. Hertz considers a series of possible foundations for mechanics, in the interest of finding a secure conceptual basis for mechanical theories. Cohen argues that Hertz's analysis can be completed, and his goal achieved, by means of a philosophical examination of the role of mathematical principles and fundamental concepts in scientific theories.

This thesis explores how and why two capitalistic American corporations were granted access to the Soviet Union's internal market. For decades communist leadership railed against what they termed "cheap bourgeois consumption," yet in 1972 Pepsi-Cola became the first officially sanctioned American consumer product in the USSR. Eighteen years later, McDonald's would become the first American restaurant to open in the Soviet Union. Both companies became deeply involved in Cold War politics and diplomacy, with high-ranking officials from both sides taking part in the negotiations to bring these companies into the country. These two case studies shed light on a seldom-covered aspect of American-Soviet economic relations and cultural exchange.
